![Question 3:
The question concerns hypothesis testing.
(i) Based on the following article (Sadleir, Paul HM, et al. Relationship of
perioperative anaphylaxis to neuromuscular blocking agents, obesity, and
pholcodine consumption: a case-control study. British Journal of Anaesthesia 126.5
(2021): 940-948.), the Australian Government banned the use of PholCodine.
Focussing on the contents of Table 4 of the paper (reproduced below), please
argue against the Australian Governments decision, taking care to point out any
limitations in your argument.
